Both Woodruff keys have fallen out of the windshield wiper arms where they attach to the wiper linkage. Without the Woodruff keys in place during operation, the windshield wipers easily detach from the wiper linkage.

What stands out
Of the 8 model years of Ford F-250 we track for visibility problems, this one carries the most owner complaints on file — 12.
No new NHTSA visibility complaint has been filed on this vehicle in over 3 years — the issue may be aging out of the active population.
The failure pattern owners describe
The primary complaint across this cluster centers on Woodruff keys (the small retaining pins) falling out of the windshield wiper linkage assembly. When these keys dislodge, the wiper arms detach from the linkage during operation, creating a sudden loss of visibility. One owner experienced this at around 8,000 miles while driving. Ford issued recall campaigns 21V090000 and 22V250000 to address this issue starting in early 2022, but owners consistently report that recall parts have been unavailable for extended periods—months past what most consider reasonable. Some dealers have refused to perform the repair, advising owners that the work risks cracking the windshield and that owners would bear replacement costs. One complaint describes the rear window spontaneously shattering at 49,000 miles immediately after remote starting, with the dealer unable to determine cause and the manufacturer offering no assistance. A single complaint mentions defective mirrors but provides no specifics. The core problem: wiper detachment creates dangerous visibility loss in rain, and the manufacturer's recall execution has stalled on parts availability.

Failure modes owners describe
Woodruff keys falling out of wiper linkage
The Woodruff keys that secure the windshield wiper arms to the wiper linkage have detached. When this happens, the wiper arms themselves detach from the linkage during operation, causing immediate loss of visibility.
When: One owner reported failure at approximately 8,000 miles; most owners have not experienced failure yet but received recall notices
Symptoms owners cite: Wiper arms detach from wiper linkage during operation; Loss of windshield visibility in wet conditions; Wiper blade arm becomes inoperable and separates from vehicle
Repairs/costs cited: Recall remedy involves replacing the wiper linkage assembly. At least one owner declined repair after being told the remedy might crack the windshield and that the owner would bear the cost of windshield replacement if breakage occurred.
Recalls/TSBs owners mention: NHTSA Campaign Number 21V090000 and Campaign Number 22V250000 issued for visibility. Multiple owners report that recall parts have been unavailable for extended periods, with manufacturer delays exceeding what owners considered reasonable timeframes.
Rear window sudden failure
The rear window spontaneously shattered without apparent external cause or activation of the rear defroster. Dealer was unable to determine the cause.
When: At approximately 49,000 miles
Symptoms owners cite: Rear window suddenly exploded and shattered; Failure occurred immediately after remote starting vehicle
Repairs/costs cited: Vehicle was not repaired at time of complaint. Cause undetermined by dealer.
Recalls/TSBs owners mention: Manufacturer was notified but offered no assistance.
